3 Terms and Definitions
GB/T 12604.1 defined and the following terms and definitions apply to this document.
3.1
Sound when flight-time
Time of sample required ultrasound through. According to their size can be determined whether there are defects.
3.2
The first wave of first-wave
Ultrasonic flaw detector receiving the first wave waveform. Depending on the shape and amplitude of the waveform can determine whether defective.
3.3
Amplitude amplitude
The size of the waveform change ultrasonic testing samples produced, usually the amount of attenuation to represent.
4 principle of the method
The use of non-metal detectors produce low-frequency pulses through the probe (wafer) electro-acoustic converting incoming sound waves propagate inside the specimen sonic
Encountered acoustic impedance dissimilar (eg defects) interface, the reflected sound waves will occur. By the probe acoustic energy into electrical impulses displayed on the oscilloscope screen, root
According to the sample and the speed of sound wave type, to judge internal defects specimen.
5 device
5.1 ultrasonic flaw detector
Technical indicators 5.1.1 flaw detector test shall comply with the relevant testing technical conditions, flaw detector test should be conducted regularly.
5.1.2 ultrasonic detector operating frequency should not exceed 2.0MHz; cathode blocks for the operating frequency of testing is generally not more than 1.0MHz.
